RITTER BBFS+ Gas Analysis

»MultiGas« Sensors for BBFS-9 & BBFS-18

The RITTER Biogas Batch Fermentation System »BBFS« allows the world-wide unique combination of:

  • … biogas fermentation tests
  • … data acquisition of volume and flow rate
  • … gas analysis of CH4 and CO2 as an option

… from up to 18 gas sources.

For this purpose, 9 high-precision RITTER »MultiGas« NDIR (non-dispersive infrared) Sensors are installed in one casing. Up to 2 casings can be attached to the rack of the BBFS.

These sensors provide the gas analysis of biogas (and many other gases) used in R&D labs. This sophisticated technology in combination with the RITTER Biogas Batch Fermentation Systems BBFS-9 and BBFS-18 allows the exact analysis of biogas from up to 18 fermentation bottles. It is a powerful tool for evaluation of biogas fermentation science.

Please use the »MultiGas« Sensors Checklist to receive a customised solution to your measurement and gas analysis requirements:
